Lapho ushaya futhi ugoqaisitembu sensimbi, indawo yokuguqulwa ngokuyisisekelo ilinganiselwe ngaphakathi kwe-fillet of die.Ngaphansi kwesenzo sokucindezelwa kwe-unidirectional noma i-bidirectional tensile, ukuwohloka kwe-tangential elongation kukhulu kunokwakheka kokucindezelwa kwe-radial, okuholela ekuncipheni kogqinsi lwezinto.Umlomo wonqenqema oluqondile lwembobo ye-flanging uncishisiwe uze ufike phezulu.Lapho ukushuba kuncishisiwe kakhulu futhi ukwandiswa kwempahla kudlula ukwelulwa komkhawulo wezinto ezibonakalayo, lokho okubizwa ngokuthi ukuphuka kwe-p kwenzeka (uqhekeko oludalwe ukunwebeka ngokweqile kanye nepulasitiki enganele yento ebizwa ngokuthi i-force anus fracture; ukuqhekeka okubangelwa ukweqisa. ukwakha amandla namandla anganele wento ebizwa ngokuthi ukuphuka).Lapho ushaya ngesibhakela futhi uphephuka, lapho i-coefficient K evulekayo iba mncane, izinga lokuguquguquka likhulu, futhi lapho kuncishiswa ukushuba komlomo onqenqemeni oqondile, kuba lula ukuqhekeka.Ngakho-ke, ukuncishiswa kogqinsi komlomo wonqenqema ome mpo akunakuzitshwa lapho kuvuleka.
1.Ukuqhekeka kwenzeka esiyingini sokuvuleka kwembobo ebhoboziwe.Isizathu esiyinhloko ukuthi ingxenye ebhontshiwe ye-pre hole inezindawo ezidabukile kanye ne-burr, lapho kunephuzu lokugxilisa ingqondo.Phakathi nenqubo yokuguqula imbobo, ipulasitiki yale ndawo impofu futhi kulula ukuqhekeka.Ukusetshenziswa kwezinto ezinokwelulwa okuhle kungakhuphula izinga le-deformation ye-punching hole flanging futhi kunciphise ukuqhekeka kwe-hole flanging.Uma ukubunjwa kuvunyelwe, ububanzi be-pre hole buzokwengezwa ngangokunokwenzeka ukuze kuncishiswe ukuguqulwa komgodi, okusiza ukunciphisa ukuqhekeka komgodi.Uma isakhiwo sivuma, izinto ezincanyana zizosetshenziswa ngangokunokwenzeka ukuze kwandiswe ububanzi obuhlobene (D 0/t) bembobo yangaphambili, okuwusizo ekunciphiseni amathuba okuqhekeka kwembobo.Lapho uklama isikhunta, kungcono ukuthatha i-parabolic noma i-spherical shape ye-punch flanging, engakhuphula ukuguqulwa okuvumelekile kwezinto zendawo futhi kunciphise ukuqhekeka.Ngesikhathi sokugxiviza, isiqondiso sokubhoboza kanye ne-flanging singaphambana nokushaya kanye nokubhoboza ngaphambili, ukuze i-burr itholakale ngaphakathi kwe-flanging, enganciphisa ukuqhekeka.
2. Ngemuva kokuthi imbobo yokugxiviza ne-flanging ivaliwe, umgodi uyancipha, i-flange ayiqondile, futhi ububanzi bembobo buba buncane, okuzokwenza kube nzima ukugoqa ngesikhathi somhlangano.Izizathu eziyinhloko ze-necking yi-springback yezinto ezibonakalayo, futhi igebe z/2 phakathi kwe-punch kanye ne-die likhulu kakhulu.Izinto ezisebenza kahle zisetshenziswa ekukhiqizeni, nge-rebound encane, engathuthukisa inkinga yentamo.Lapho uklama idayizi, ukukhetha imvume efanele phakathi kokufa kweduna nensikazi kungaqinisekisa ukuthi i-flanging flange imile.Ukuvunyelwa phakathi kwe-punch kanye ne-die ngokuvamile kungaphansi kancane kunogqinsi lwempahla.
3. Ukuphakama okunganele kwe-flanging flange kunciphisa ngokuqondile ubude be-screw yesikulufu kanye nembobo futhi kuthinta ukuthembeka kokuxhumeka kwesikulufu.Izinto ezithinta ubude be-flange bokuvuleka kwesitembu zifaka phakathi ubukhulu bembobo yangaphambili eyeqile, njll. Khetha ububanzi bembobo encane ukuze ubhoboze ngaphambili ukuze ukhuphule ubude bokuphenduka kwembobo.Uma i-diameter ye-pre hole ingenakuncishiswa, ukucwiliswa nokuvuleka kungathathwa ukwenza udonga lube mncane ukwandisa ukuphakama kwe-flanging flange.
4. Impande engu-R yokubhoboza nokuphephuka inkulu kakhulu.Ngemva kokuvuleka, impande engu-R inkulu kakhulu, okuzokwenza ukuthi ingxenye enkulu yempande ingathinteki nesikulufu ngesikhathi sokuhlanganiswa, inciphisa isikulufu ngobude besikulufu kanye nembobo, futhi kunciphisa ukwethembeka kokuxhumeka kwesikulufu.Impande engu-R yembobo evulekayo inkulu kakhulu, ehlobene nogqinsi lwempahla kanye nomcu wokungenela we-stamping flanging die.Ukuqina kwempahla, impande engu-R izoba nkulu;Uma i-fillet ibe nkulu emnyango wefasi, iba mkhulu u-R empandeni yembobo evulekayo.Ukuze unciphise impande engu-R yembobo ye-flanging, izinto ezincane kufanele zikhethwe ngangokunokwenzeka.Lapho uklama idayi, izibopho ezincane emnyango wesifazane kufanele zenziwe.Lapho kusetshenziswa izinto eziwugqinsi noma izibopho emnyango wefasikazi lingaphansi kokuphindwe izikhathi ezi-2 ubukhulu bezinto ezibonakalayo, i-punch flanging izoklanywa ukukhulisa ihlombe ngokubunjwa, futhi impande engu-R izobunjwa ekugcineni kokunyathela. unhlangothi, noma inqubo yokuma izongezwa ngokuhlukana.
5. Lapho izimbobo zokubhoboza kanye ne-flanging zicutshungulwa ngokubhoboza nokufaka izinto ezilahlwayo, asikho isakhiwo esihambisanayo esihambisana nokufa kwe-concave ngesikhathi sokushaywa, futhi izinto ezisetshenziswayo ziyakhishwa.Izinto ezilahlwayo zokubhoboza zinganamathela ngokungahleliwe onqenqemeni lwembobo, okuholela ekubhujisweni kwemfucuza kaningi.Ukudlidliza kwezinto ezilahlwayo ngesikhathi sokuthatha nokuphatha kulula ukuhlakazeka endaweni yokusebenza yefa noma ingxenye, okubangela ukukhubazeka kwe-indentation ebusweni bengxenye, okudinga ukulungiswa ngesandla, Kunzima ukuhlangabezana nezidingo zangaphandle. izingxenye ezizolungiswa, futhi zingalahlwa kuphela, zimoshe abasebenzi nezinto zokwakha;Imfucumfucu yezimbobo ze-flanging, uma ilethwa emhlanganweni jikelele, kulula ukusika ama-opharetha futhi ithinte i-screwing;Ezingxenyeni zikagesi, njengemfucumfucu ye-flanging hole, kulula ukubangela i-short circuit uma iwela ezingxenyeni zikagesi ngesikhathi se-screw, okuzoholela ezinkingeni zokuphepha zikagesi.
